In the case where the living tissues in the patient's body is resected as well, it is possible to suture the resected portion immediately without replacement with another treatment device after resection. Thus, prevention of bleeding from the resected portion or earlier repair of an ulcer that occurs with the resected portion can be carried out for the patent lowly invasively and easily.

An endoscopic treatment device is used with an endoscope. This treatment device includes a transmission member with a flexible structure having a distal end portion to be inserted into a body and can be operated outside the body, a push rod coupled to the distal end portion, and first and second connecting members rotatably coupled to the push rod. The treatment device further includes first and second arm members rotatably coupled to the distal end portion of the connecting member, a holding member rotatably holding the respective arm at a predetermined interval therebetween, and first and second actuating members integrally formed with the arm members and can open/close when the transmission member actuates the first and second connecting members and the first and second arm members through the push rod. This device also includes a needle mounted on at least one of the first and second actuating members.

A semiconductor memory device has a plurality of word line provided on a semiconductor region, extending in a row direction, a plurality of bit lines provided in the semiconductor region, extending in a column direction, and a plurality of memory elements provided at intersections between the plurality of word lines and the plurality of bit lines. Each word line provides a first gate electrode in the corresponding memory element. A lower portion of a side surface of each word line in a direction parallel to an extending direction of the word line is perpendicular to a main surface of the semiconductor region. An upper portion of the side surface is inclined so that a width thereof becomes smaller toward a top thereof.
